ERROR: Could not find a version that satisfies the requirement monotonic-align==0.0.3 (from versions: 0.0.3)
ERROR: No matching distribution found for monotonic-align==0.0.3
WARNING: You are using pip version 21.2.4; however, version 23.0 is available.
You should consider upgrading via the 'C:\Users\Administrator\AppData\Local\Programs\Python\Python39\python.exe -m pip install --upgrade pip' command.

Start by reproducing the reported Python 3.9 installation of monotonic-align==0.0.3 and inspect the shown setup.py failure, especially the missing Cython module. Determine whether the dependency can be installed successfully in the repository's supported environment; done means the reported package installation no longer fails for the documented setup.
